Abstract

Location-Routing Problem (LRP) can model several life situations. In this paper we study The Capacitated Location Routing Problem (CLRP) which is defined as a combination of two problems: the Facility Location Problem (FLP) and the Vehicle Routing problem (VRP). We propose a two-phase approach to solve the CLRP. The approach is based on Simulated Annealing algorithm (SA) and Ant Colony System (ACS). The experimental results show the efficiency of our approach.
